See a solution process below:

Explanation:

First, group and combine like terms on the left side of the equation:

2x + 12 - 7x = -2

2x - 7x + 12 = -2

(2 - 7)x + 12 = -2

-5x + 12 = -2

Next, subtract color(red)(12) from each side of the equation to isolate the x term while keeping the equation balanced:

-5x + 12 - color(red)(12) = -2 - color(red)(12)

-5x + 0 = -14

-5x = -14

Now, divide each side of the equation by color(red)(-5) to solve for x while keeping the equation balanced:

(-5x)/color(red)(-5) = -14/color(red)(-5)

(color(red)(cancel(color(black)(-5)))x)/cancel(color(red)(-5)) = 14/5

x = 14/5
